L'américain Walter Williams (Mason University) plaide pour la liberté de l'enseignement et le désengagement de l'Etat des programmes scolaires :

(...) Prayers in school, sex education and "intelligent design" are contentious school issues. I believe parents should have the right to decide whether their children will say a morning prayer in school, be taught "intelligent design" and not be given school-based sex education. I also believe other parents should have the right not to have their children exposed to prayers in school, "intelligent design" and receive sex education.
The reason why these issues produce conflict is because education is government-produced. That means there's either going to be prayers or no prayers, "intelligent design" or no "intelligent design" and sex education or no sex education. If one parent has his wishes met, it comes at the expense of another parent's wishes. The losing parent either must grin and bear it or send his child to a private school, pay its tuition and still pay property taxes for a school for which he has no use. (...)
